Is there a pin-compatible replacement for LQG15HS4N7S02D?

Yes, several inductors share the same 0402 package and pinout. However, no direct drop-in replacement with identical 4.7nH inductance and 700mA current rating has been identified. Candidates like LQG15HS3N9S02D are pin-compatible but require review of their different inductance value.

What risks should I check before replacing LQG15HS4N7S02D?

The primary risk is inductance mismatch. Most alternatives have a lower inductance (e.g., 3.9nH vs. 4.7nH), which can affect the performance of RF filters, matching networks, or DC-DC converters. Always verify the impact on your circuit's frequency response and stability.

Finding a substitute for the Murata LQG15HS4N7S02D 4.7nH inductor requires matching its 0402 package, high frequency characteristics, and 700mA current rating. Alternatives exist with slightly different inductance values that may require circuit validation.

AI replacement insight

Electrical riskmedium

Inductance change requires validation in the application.

Package risklow

The 0402 package is standard and widely available.

Can it be replaced directly?

No direct drop-in replacement with identical key parameters has been found. Alternatives require parametric trade-offs, primarily on inductance.

Best replacement path

Use a part from the same Murata LQG15HS series with a close inductance value, like LQG15HS3N9S02D, and verify circuit performance.

Main risk

Inductance deviation from the target 4.7nH value will impact circuit tuning and performance.

Recommended alternatives

Same series part with higher current and lower DCR, but inductance is reduced to 3.9nH.
